Study on Crack Resistance of Hydraulic Roller Compacted Concrete Dam with Fly Ash Admixture
نویسندگان
چکیده
With the continuous improvement of level construction industry in modern industry, at same time, requirements for crack resistance concrete dams are also higher and higher. In preparation stage experiment, corresponding experimental materials equipment provided. order to ensure that can meet workability strength grade, proportion is designed; During activity characteristics fly ash admixture extracted, particle size distribution tested, fracture data hydraulic RCC dam monitored; The results show when ratio cement 0.7:0.1, number, width area cracks minimum, which proves under this more suitable engineering.

Investigation of Nonlinear Behavior of Material on Seismic Performance of Roller Compacted Concrete Dam
In this research, the effect of nonlinear behavior of concrete on seismic performance of roller compacted concrete (RCC) is discussed. Nonlinear behavior of material shows the behavior close to reality due to use of all structural capacity and it is considered the most appropriate method for design. So in this paper, by using the appropriate definition of nonlinear behavior of RCC, the Ansys so...
متن کاملExperimental Study on Durability Improvement of Fly Ash Concrete with Durability Improving Admixture
In order to improve the durability of fly ash concrete, a series of experimental studies are carried out, where durability improving admixture is used to reduce drying shrinkage and improve freezing-thawing resistance. The effects of durability improving admixture, air content, water-binder ratio, and fly ash replacement ratio on the performance of fly ash concrete are discussed in this paper. ...
متن کاملPredicting the deformation of roller compacted concrete dam using least squares support vector machine
As a new type of dam, roller compacted concrete dam (RCCD) develops very fast in recent years. Deformation plays an important role in the RCCD’s safety. The deformation of RCCD is influenced mainly by three parts: water pressure, temperature and time effect. As to any of the three parts, there are many factors. Therefore, the deformation of RCCD is a complicated system. The least squares suppor...
متن کاملFire Resistance of Concrete with Fly Ash Content – Experimental Analysis
The paper presents results from three large scale experiments on seven reinforced concrete panels obtained during an extensive experimental program. This was aimed at possible application of cement reduced (fly ash replaced) concrete in the production of precast segmental linings for tunnels created by a tunnel boring machine (TBM). In particular, this paper is focused on the comparison of fire...
